# init(animationCurve:)

Initializes the object with the specified UIKit timing curve.

## Declaration

```swift
init(animationCurve curve: UIView.AnimationCurve)
```

## Parameters

- `curve`: The UIKit timing curve to use for the animations. You can specify a linear animation or an animation whose initial or final speed is slightly slower.

## Return Value

Return Value An initialized timing parameter object or nil if the object could not be created.

## Discussion

Discussion Use this method to create a timing curve that uses the standard UIKit timing curves such as UIView.AnimationCurve.easeIn, UIView.AnimationCurve.easeOut, UIView.AnimationCurve.easeInOut, or UIView.AnimationCurve.linear.
